To all whom it may concern.' Be it known that I, GEORGE E. STEVENS, a

Lynn, in the county of Essex and State of Massachusettsxhave inventedcertain new and useful Im rovements in Electric Heaters, of which t efollowing is a specification.

This invention relates to electric heaters and has for its object theprovision of a de- 'vice of this character ada ted for atmosphericheating urposes,-w ich is self-contained and simpe in construction andat the same time thoroughly reliable, safe and efficient.

My invention relates more specifically to ,the production of an electricheating device of the type known as a foot warmer, one of the objectsbeing to produce a heater which isin the nature ofa foot rest, which maybe 'move'd from place to place, and which is strong and at' the sametime of alight construction.

My invention therefore consists of the features of construction and thearrangement and combination of elements hereinafter set forth.

In the acoompanyingdrawings in`which I have shown my invention embodiedin a concrete structure, Figure 1 is ,a plan view partly in section ofone formdof my invention; Fig. 2is a'sectional view of the same taken onthe line 2 2 of Fig. '1; Fig. 3 is a plan view of a modified form of myinvention; and Fig. 4

is an end view partly in section of the same.

Referring to the drawings (Figs. 1 and 2) 10 re resents the sides of abox, preferably of meta having a bottom or base 11`-secured thereto madeof some material, such as wood, the bottom surface being preferably offelt 12. The box is open at the top and an electric heating unit 13 ofan elongated type, as shown, is mounted longitudinallyfand centrally ofthe box. This unit is preferably mounted in bearings 14 so as to revolvetherein. The unit may be of any desired type but the particularstructure forms no part of my invention. For purposes of illus-- trationI have shown the unit of the type described and claimed in my previouspatent No. 803,795. The leads for this heating unit are brought inthrough the insulating sleeve 15 and are connected at opposite ends ofthe unit by means of the terminals 16, each adapted to cooperate with asocket 17.

casing in the form of wings 19' mounted on rods 20 which pass throughthe'ends of the strips. The wings 19 are bent in the arc of a circle ofwhich the axis' of the unit 13'is the center, and the sides of the boxare brought in to meet this wing so as to make a close joint and preventair from going out exce t through the space between the strips. T e endsof the wings are bent into the form of a stop 21 sol as to limit themovement of the Strips. f These strips are of thin metal and so shapedthat they will conduct the heat from the unit out to their ends so thatwhen the current is turned on, the strips will be heated throughouttheir length and the feet may be warmed by placing them thereon. Theangle of support may be changed b a sim le movement of the ankles whichwi shift t e top on its pivot.

Figs. 3 and 4 show another form of the device in Whichthe top of the boxis arranged' at a iixed angle. In this case the top 22 is arranged atthe inclination shown and the These stri s have a length has the eect ofcausing the heat to difuse as it is limited by the scope of the claimsannexed hereto.

What I claim as new and desire to secure by Letters Patent of the UnitedStates, is-

1. An electric heater comprising a box having a movable apertnred top,and an electric heating device arranged 'to distribute heat throughoutthe area of said top.-

2. An electric heater comprising a box having a pivoted apertured topand an electric heatmg device arranged to 'distribute heat throughout.the area of said top.

3. An electric. heater comprising a box-- having an apertured topconsisting off an' elongated heating unit and spaced strips in heatconductive relation thereto.

4. An ectric. heater comprising a box having an apertured top pivotedfor movement in a vertical plane, an elongated heating unit extendingcentrally thereof, and means for distributing the heat throughout thearea of said top. i

5. An electric heater comprising a box having an apertured topconsisting of an elongated heating unit and spaced strips inheat-conductive relation to the unit'pivoted for movement in a verticalplane about the v axis of the unit. l

6. An ,electric heater comprising a box .having an apertured toppivotedfor movement in a vertical plane, said box consisting f GEORGE E.STEVENS.
